For laboratory appliances requiring a deeper vacuum source KNF announces the release of its latest vacuum pump, the N920. This revolutionary pump provides high flow at near-maximum vacuum, the region where traditional diaphragm pumps have the most significant reduction in performance. It achieves up to 1.3 m3/hr pumping speed and a rapid 1.5 mbar (abs) ultimate end vacuum.
This pump is available as a portable pump (shown) or as an OEM model with a DC or AC power connection. As a further convenience, this pump is equipped with a manual control or analog motor speed input that enables you to vary the output of the pump to match individual system needs. This allows for quieter operation and an increased lifetime. Its unique three head design incorporates inter-head connections, and means fewer moving parts, increased reliability and less expensive maintenance.
The universal motor is capable of operation on 24V DC, or 90-264V AC at 50-60Hz. The N920 offers excellent long term vacuum stability with its patented diaphragm stabilization system, and high efficiency valves which can be used in roughing and backing applications, including mass spectrometers and leak detectors. This pump is available in PPS and aluminium versions for pumping slightly aggressive or corrosive gases and vapours.
